Outline

• Review of Heuristic Evaluation

• Web Design Process, Specialties & Artifacts

• Detailed Design Example

• Web Design Patterns


Review of Heuristic Evaluation• Have evaluators go through the UI twice• Ask them to see if it complies with heuristics

– note where it doesn’t & say why

• Combine the findings from 3 to 5 evaluators• Have evaluators independently rate severity• Alternate with user testing


Good Web Site Design Matters

Good Web Site Design can Lead to Healthy Saleshttp://www.nytimes.com/library/tech/99/08/cyber/commerce/30commerce.html

• NY Times, Aug 30 1999, on IBM Web site– “Most popular feature was … search …

because people couldn't figure out how to navigate the site“

– “The second most popular feature was the help button, because the search technology was so ineffective.”

• After redesign– use of the "help" button decreased 84 percent

– sales increased 400 percent


Web Design Process


Design Specialties

• Information Architecture– encompasses

information & navigation design

• User Interface Design– also includes

testing & evaluation

Information Architecture

User InterfaceDesign

Information Design

Navigation Design

Graphic Design

Usability Evaluation


Artifacts of Design Practice

• Designers create representations of sites at multiple levels of detail

• Web sites are iteratively refined at all levels of detail

Site Maps Storyboards Schematics Mock-ups


Site Maps

• High-level, coarse-grained view of entire site


Storyboards

• Interaction sequence, minimal page level detail


Schematics

• Page structure w/ respect to information & navigation


Mock-ups

• High-fidelity, precise representation of page
